SPECIFICATION forming part of Letters Patent No. 368,069, dated August 9, 1887.

Application filed February 17, 1882. Serial No. 52,947. (No model.)

To all whom it may concern:

Be it known that 1, WILLIAM T. CARROLL, of Worcester, county of Worcester, State of Massachusetts, have invented an Improvementin Supports for Spinning-Spindles, of

which the'following description, in connection 2 located above the whirl and means to hold thesaid bearing, as will be described; also, in

a supporting-tube closed at its bottom to form an oil-chamber, and a detached lower bearing externally smallest at itslower end and enlarging upward toward the whirl and free at its lower end to move in the snpportingtube with the foot of the spindle as it seeks its true center of rotation, combined with means to restrain the said hearing from rotation within the said supporting-tube, substantially as will be described; also, in the combination of a supportingtube having a closed bottom with a loosely-held or detached bearing supported at its lower end within said tube, the bearing tapering from its center to its ends and movable bodily throughout its length within the supporting-tube and leaving a chamber between it and the said tube for oil; also, the combination of a supporting tube having a closedbottom with abearing supported therein at its lower end, the bearing tapering from its center toward its lower end, thereby permitting the bearing to oscillate within the said tube, and leaving a chamberbetween it and 5 the said tube for oil, and means for positively restraining the hearing from turning.

By the employment of the auxiliary bolster or upper bearing above the whirl, the spindle when it is deflected or tipped from its vertical position will come in contact with the boling-shell, that being the approved plan to secure'the most perfect alignment of the bolster with the spindle. I

The supporting-tube for the lower bearing being closed at its bottom enables the formation ofa chamber to contain oil, and also permits the said bearing to be dropped loosely into the said chamber and be interposed between the spindle and the said tube, where it is free to move laterally or tip or rock in presence of the oil in the said chamber.

' I have dispensed with all fibrous packing between the lower bearing and its surround- 7 ing supporting-tube, and to keep the said hearing from rotating, but yet permit it to move in the said supporting-tube as the lower end 'of the spindle moves to find its true center of rotation, I have employed a pin-and-slot connection between the said tube and bearing.

The drawing shows in vertical section the principal part of a spindle, its whirl, its any iliary bolster or upper bearing, and the shell Within which it is placed, together with the 85 lower bearing and supporting-tube and their connection, they being combined and arranged to illustrate my invention.

. The supporting'tube c, held in suitable manner in the rail a receives within it a detached lower bearing, 12, shown as open at its lower end to permit the pintle c of the spindle c to pass through it and rest on the foot-step 2, forming part of thesaid supporting-tube. This detached bearing b is so shaped externally that 9 5 it may move within the tube a, in which it is placed loosely, and, as herein shown, its outer portion is of greater diameter near its center than at its ends.

The bearing 7) is prevented from rotatingin I00 the tube a by means of a pin, 0, connected with the tube a and extended into a slot in the said bearin lhe bearing 1) is described as detached, or, in other words, it is notimmovabl y fixed with relation to or in the tube a, buthas just enough play therein to permit the bearing to move sufficiently by the action of the spindle within it to compensate for and neutralize the jar due to the rapid rotation of the spindle when unevenly loaded; but in no event can the hearing 1) rotate freely within the tube or well with the spindle, for the said hearing has co-operating with it a pin or projection which restrains its rotation with the spindle.

The sleeve-whirl (1 (1. which may be of any usual ednstruction, is extended down over and about and so as to inclose the tube a.

I have found that a spindle of the kind described may be materially improved as to its action by combining with it above the whirl an auxiliary bolster or npperbcaring, c, it being preferably ol'sueh internal diameter with relation to the diameter of the spindle within it that when the spindle is running perfectly true it will not touch the said auxiliary bolster or upper bearing; but as soon as the spindle from any cause is deflected from true perpendicular position it will strike against the said. auxiliary bolster or upper lateral bearing, and its tipping movement will be immediately checked and counteracted. This auxiliary bolster or upper hearing will be supported in an outer shell, f, held in an upper rail, g, and the shape of the auxiliary bolster or upper bearing externally and its support within the said shell, as shown, is such that the said auxiliary bolster or upper hearing may rock to a limited extent upon that portion of its perimeter which lits the shell.

I am aware that a spindle-bearing has been placed in asupporting-tubein connection with an independent step, the said bearing being surrounded by an elastic or fibrous packing, and such I do not claim; butin this myinvention the bearing I), placed loosely in the tube a, is free to move with the spindle as its foot moves laterally to find its true center of rot-ation, yet the said bearing moving in the chamber of the tube a is positively restrained from rotation with the spindle by reason of the slotand-pin connection shown, the size of the pin and slot being such as not to interfere with the rocking and tipping movement of the lower bearing, 11, as the foot of. the spindle moves or shakes.

I am aware that United States Patent No. 153,99l describes that a step-socket shown therein is made with a cylindrical bore or chamber of a definite depth, and that a bushing made of a smaller diameter than the bore excepting at one part, which is made larger and of a spherical form and of a diameter to accurately lit the cylindrical bore of the socket, is inserted in the said socket, the bottom of the bushing resting upon the bottom of the bore of the socket; but in such a contrivance the bushing cannot move bodily in a lateral direction throughout its length as in this my invention.

I claim 1. The spindle, its whirl, the supportinglube, and the movable hearing within it, co1nbined with a loosely-held auxiliary bolstcrlocated above the sleeve-whirl, and with the bolster-rail and means to hold thesaid auxiliary bolster, substantially as and for the purposes Set forth.

2. The spindle, its whirl, a supporting-tube, and a loosely-held or detached bearing made laterally movablcbodily throughout its length, combined with an auxiliary bolster or upper bearing located abovethe said whirl, and with means to hold the said bolster, substantially as described.

3. The spindle provided with awhirl, asupporting-tube, a detached lower lateral bcaring therein, and means to restrain the said hearing from rotation with the spindle, combined with a loosely-held auxiliary bolster or upper lateral bearing, and with means to hold or support the said bolster above the whirl, substantially as described.

4. The spindle provided with a whirl, asupporting-tnbe, a detached bearing made laterally movablc therein throughout its entire length, and means to restrain the said hearing from rotation with the spindle, combined with an upper auxiliary bolster, and with means to hold or support the said bolster above the whirl, substantially as described.

5. A supportingtube closed at the bottom to form an oil-chamber, a detached lower bearing enlarging from its lower end upward toward the whirl and free at its lower end to move in the supporting-tube with the foot of the spindle it seeks its true center of rotation, combined with means to restrain the said bearing from rotation within. the said supporting-tube, substantially as described.

6. The combination of a supporting-tube having a closed bottom with a loosely-held or detached bearing supported at its lower end within said tube, the bearing tapering from its center to its ends and movable bodily throughout its length within the supportingtube, and having a chamber within the said tube for oil, substantially as described.

7. The combination of a supporting-tube having a closed bottom, with a bearing supported therein at its lower end, the bearing tapering from its center toward itslowcr end, thereby permitting the bearing to oscillate within the said tube, and leaving a chamber between it and the said tube for oil, and means for positively restraining the hearing from turning, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

\VILLIAM T. CARROLL.
